PEGIFIGATION forming part of Letters Patent No. 509,011, dated November 21, 1893.

Application filed September 28, 1389. Serial No. 325,374:- (No model.)

To all whom it may concern.-

.Be it known that I, J OSEF WINTER, man ufacturer, ofAschersleben, in the Kingdom of Prussia and German Empire, have invented a new and useful Husking-Machine for Rice,

anism for controlling the length of time for husking a certain quantity of grain or other material during a continuous charge and discharge, of which the following is a specification, reference beinghad therein to the ac- My invention relates to husking or decortieating machines, and consists in various features hereinafter set forth and claimed.

In the drawings, Figure l is alongitudinal sectional view of the machine on the line 1-1 of Fig.2; Fig. 2 an end elevation, partly in section; Fig. 3 a vertical sectional view on the line w-x of Fig. 1; Figs. 4, 5, and 6, views illustrating the construction of the rotating cylindrical shell or casing, and Fig. 7a vertical sectional view on the line y y of Fig. 1.

Upon a rotary shaft f, which is journaled in suitable bearings in the frame of the mainder, comprising in the present instance an. open ended cylindrical shell 6 having a covering of emery, sandstone or the like. This husking wheel or cylinder is inclosed by a; box or casing, also journaled in suitable bearings and adapted to turn or rotate in' a d'recder. This casing comprises two I z Z having openings at the centef throng which the material is respectrvelyfed and discharged; said disks being also provided with lateral hollow gudgeon's afiord'ing a support for the casing, as shown in Fig. 1. Upon the" inner face of each disk is a series of annularconcentric grooves O to receive the ends of the bars which .form the active or working face of the casing,the bars being held in place by means of suitable tie rods,--shown in Figs. land 2,-connecting' the disks. The

prise a number of inclined transverse ribs h and a series of longitudinal ribs h which are so arranged as to form a series f cells or pockets. The inclination of the fribs h results in the formation, on the inner face of the spiral channel composed of a number of independent cells. The ribs h are shorter, radially, than the ribs h, hence the grains are prevented from working directly from one end of the machine to the other. When the abrading or husking cylinder wears away, the bars may be set closer to the cylinder,the annular grooves O permitting such adjustment. y 1

In order to impart motion to the shell or casing (which is itself inclosed) the latter is provided with a gear ring k,(F igs. l and 2) which meshes with a pinion t secured to a shaft journaled in the frame of the machine,

. the said shaft having a band wheel t to receive a belt from wheel t carried byshaft f. The material to be husked is fed continuously through tube a, (Figs. 1, 2 and 7) by means of the feed roller b, into and through tary casing. The material after working its ered or falls into the radial'tubes d on the inner face of the said disk, and passes into the brushing chamber formed by enlarging the gudgeon of said disk Z as shown in Figs. l and 3. In this chamber the grain is subjected to the action of brush m secured to shaftf, and finally discharged through spout d ,-the dust given off during the brushing as well as that given off during the husking berespectively. In order to permit the dust to escape from the rotating shell or casing, the

, bars forming the perip cry-of the game, have narrow recesses alon' one edge,see Fig. 6,-- which allow the dus topass outward. When, in the rotation of the shell or casing, one of its cells filled with grain has passed beyond the level of the axis; the grains slip from the cell and fall downward into another cell, are raised by this cell, again discharged, and so on, until they have been carried laterally by the spiral arrangement'of the cells over to the discharge side of the machine. It is during their fall from the cells that the grains by dropping upon the peripheryof the husking cylinder are subjected to the abrading action of the latter. By giving the-ribs h'asuitable shape, the grains may be caused to slip endwise or sidewise from the cells onto the cylinder. Where the ribs are of such shape that way over toward the opposite disk Z is deliving carried away through the pipes r and r the hollow gudgeon c of thedisk Z of the rothe corners of the cells are rounded as in Fig.

6, the grains assume a direction radial to that of'the shell or casing, or with their points toward the stone or cylinder; but if the cells have sharp edges the grains will assume a position therein more nearly corresponding to the axis of rotation, and will fall or roll from the cells sidewise upon the cylinder.

What I claim is- 1. In a husking machine, the combination with a rotary abrading cylinder, of an encircling rotary shell or casing having on its inner face a continuous spiral row of cells or pockets.

2. In a husking machine, the combination with a rotary husking cylinder, of an encircling shell comprising two disks and the longitudinal bars having pockets or cells.

3. In combination with the disksZ Z having each a series of annular grooves, thelongitudinal cell bars seated at their endsin the grooves; and the tie rods connecting the disks.

4. In a husking machine, the combination with a husking surface, of a shell or casing having longitudinal bars provided with l0ngitudinal and transverse ribs h and h.

5. In combination with the disk Z having the radial tubes d and the enlarged hollow gudgeon; disk Z' also provided with ahollow gudgeon and connected with disk Z; the cell bars; a shaft f passing through the disks; and an abrading cylinder and a brush carried by the shaft.

I n witness whereof I have hereunto set my hand in presence of two Witnesses.
